Referring fo 1 .to @ons d....sa.-

the improved connector comprises a substanf tially vcylindrical sectionV of terval's-l, to form resilient fingers 16. The opposite end portion of the original tube is brought together and `liet-tened at 1 7', form? ing a rear closing wall at 18forthe'interior of said tube, Which-in turn is pierced at r19 to: permit .a conductor QOtoA pass therethrough.- Said' flattened portion 17 infturn is also pierced at 21,'or securing the device by suitable means to-.any other 'supporting Vtubing 12, havg 13, but tapered member as may be desired.

. spaced. `aoles one end 31 and threaded, is at the otherend,

with the holesl33;'or asolidwasher-like member f can first 0 after which the spaced holes are ldrilled in 1t simultaneously with firmly 1against the closed end A41 thereof a washer-like member 42, which together,` with cally impossible. However, the tubular casing is such said pairs.

the end 4L is simultaneously pierced by' spaced apertures 43. To secure a conductor 44 in this form of connector, a'short piece of metal 45, preferably of the shape-as the conductor.L and in fact generally a piece of the same thing, is inserted through one of the holes 43 and one of the holes 33, while. a bare-.d section of the conductor 44 is passed through the other hole of each of the Then the plug is placed over the openend of the tube and screwed firmly into place, causing to twist into the condition and shape shown in Fig. 10. From this position it is readily seen that it is impossible to 'withdraw the main conductor from the connector, when thus assembled, without destroying the de 'vice as a whole,` or at least mutilating it to such an extent as tofmakeits re-use pract1. the strength of as to cause the conductor to break before the former yields,

y it having been found that the formation of Y the connector from thetubemakes its liabilf ity to break m'l, when comp'hprt to the usual castings employed for this purpose. In this connection, however, it iscto be noted that manlhanges in the shape and arrangement vof the various parts can be made without departing from the scope ofthe invention or from the breadth ofappended claims.

In the terminal or connector shown in Fig7 11 the tapered casing 50 ispressed from a 1 metal blank, preferably steel, while the plug 5l is formed in a similar manner, each being subsequently threaded as shown. 'The gripping member 52`is provided with resilient lingers 53, which firmly grip the conductor 54 when forced into the casing 50 by engagement With` the bushing 5 5, wh'ich inturn contacts directly with the ,conductor or other member 56, passing through oppositely posi-.

the holes33. An inter-- y'nally threaded cap' 40 has forced into it and same size and the two parallel conductorstaching portion,

siugly into the transversely elongated aperture 62 in the attenedportion 63 of the tubular member 64. Said last-named. member has inserted and secured therein a centrally apertured block 65, while the plug 66 has a centrally disposed, tapered aperture 67 into which extends the tapered gripping member 6,8. In this construction, as the plug is screwed into place within said tubular member, the coperation of the gripping member with the block 65, forces the former through the said plug, thus contracting its resilient fingers 68 about the conductor 69, and in this manner securing said conductor to the conductor 70. Said terminals are attached vand firmly cured to each other by a suitable bolt v71, which'can be removed at will, but which when in position, prevents any appreciable movement of one of said termmals with reg5 spect to the other in any direction. Having thus described my invention, what I claim and desire to protect by Letters Patent of the United States is:

l. A terminal connector, comprising a body portion formed froma tube collapsed at one end and having its walls tapered at the opposite end, in combination with a. sleeve, and yielding means ,to secure said sleeve in position 'on said body. i

2. A terminal' connector, comprising ya body portion formed from a tube collapsed at one end and having its walls 4tapered -at the opposite end and slotted to form spaced resilient fingers, in combination with a conical sleeve, and yielding means to secure said sleeve in position on said body and surrounding said fingers.

3. A terminal connector, comprising a body portion formed from a tube. collapsed at one end to form a. supporting base and h aving its walls tapered at the opposite end and slotted to form spaced resilient fingers, ii1combination with a conical sleeve, and yielding means toengage said body portion 110 and secure' s aid sleeve in position upon said@ body and surrounding saidiingrs.

4. Atrminal connector, comprising a bod Aportion formed from a tube, having its wal s pressed together at lone end to form an at-y and at its other end slotted at intervals to form yieldin grip ing me1nbers, .means to contract sai mem rs about a conductor, and yielding means integral with said last-named means and o erative to secure the same in operative relation with saidbody portion.

5. A terminal connector, comprising av body portion formed from a tube, having its walls pressed together at one end to'form an attaching portion, and at its other endy slotted at intervals to form yielding ri ping members, said members being simi ar y tapered, and a conical sleeve operative to be torced overI and bontract said members 130 about a conductor, and yielding means integral with said sleeve operative to engage said'body portion to secure the same against relativeinovement.

6. A terminal connector, comprising a body member, centrally apertured and slotted, to provide yielding gripping fingers,

and a member provided with a tapered bore and operative to be forced rectilineally over said fingers to contract the same, and yielding means integral with one of said members to secure the same together.

7. A terminal connector, comprising a bodymember centrally apertured and slotted, to provide yielding gripping fingers, aV tube provided with a tapered bore and operative to b'e forced rectilineallyover said fingers to contract the same and yielding means to secure tlon.

S. A termlnal connector, comprising a said tube in operative posibody member, centrally apertured and slot.
